The sensor is profiled and that data is in the camera in every digital
camera.  What varies is how thoroughly or well it's done.  For a lot
of my scientific work, we profile the sensor before each shot, and
they are grade 0 sensors (i.e. shown to have no flaws by repeated
testing), a lot better than even those that get put into large and
medium format camera for photographic purposes.

Even in a raw file, the processor and the firmware has to 'make' the RAW 
file.
